Why and when was lead phased out of gasoline as an additive?
Tetraethyl lead was phased out of gasoline in the United States starting in 1976 and ending in 1986. Leaded gasoline caused lead to be present in automotive exhaust, which caused an increase in the lead content in people's bloodstream, which tends to reduce I.Q. and increase antisocial behavior. Tetraethyl lead was used as an octane improver, and it also reduced valve seat wear. It damages catalytic converters, which are the primary emission control device in motor vehicles. Catalytic converters and hardened valve seats started being produced in 1975.
